Hazardous Areas Classification

It's will be a long and confusing contents through all the requirement from IEC/IECEx as well as IMO (SOLAS, IBC, IGC codes). Thus, i'll make it as short as possible to make the article with key knowledge & understanding. FIRST - WHAT'S THE PURPOSE OR HAZARDOUS AREA CLASSIFICATION? Hazardous area classification in respect of selection … Continue reading Hazardous Areas Classification


Intrinsically Safe Cable

Intrinsic safety - I.S is a protection technique for the safe operation of electrical and electronic equipment/system in Hazardous Areas where any ignition source needs to be eliminated. Electrical cables are essentially sealed from damage, external electrical or magnetic fields (EMI), and isolated from non-intrinsically safe circuits. (Avoid the increase of amperes mA in I.S … Continue reading Intrinsically Safe Cable


Continuing on MARINE COROSSION AND PROTECTION (Part 1) that we discussed about the Electro-chemical corrosion protection methods and the last remained one is called ICCP system. Reversing the current by creating an opposite potential ( ICCP : Impressed current corrosion protection ) The ICCP system, a large positive current is applied to hull and pass through … Continue reading MARINE COROSSION AND PROTECTION (Part 2)


To understand how marine corrosion protection works, it's necessary to look in more detail in to the corrosion process. In this undesired chemical effect, the material can reach with different chemicals in its surroundings. The reaction can be divided into: Chemical reaction Electro-chemical reaction These reaction take place exclusively at the surface  of material. It's … Continue reading MARINE COROSSION AND PROTECTION (Part 1)
